Welcome to the club. I have a DP35DP motherboard with 572 BIOS. I change the CPU from Q6600 to Q9650 and now the CPU fan runs at full speed all the time and the system will not restart unless it is powered down. Also, Window is not correctly recognizing the CPU. Now I need to fight to downgrade the BIOS to see if that fixes the issue. I already tried and had issues. There are still avenue to pursue to get a successful downgrade.
I posted on another thread, I solved a simalar issue by reflashing with bios 517(the bios that was flashed on the mobo). Try reflashing with 527, if not try a bios recovery to 517. then also uninstal then reinstall the Intel ME driver.
